I don't really get into the values listed on this site, but I am wondering how they become affixed to any particular card. I recently added a card to my collection, then added a second for sale. None of the users on the "have" or "want" list had values, however the card I listed for sale popped up with a value of $40. Where did this come from? I didn't enter it. Just curious. Card is 2018 Topps Update Baseball 107b Rally Goose
Update: Ok, I see price comes from an auction price.
